To all whom it may concern:

Be it known that 1. JOHN THOMAS WHIT- TOME, a British subject, and a resident of 3 Parkwood road, Tavistock, in the county of Devon,England, haveinvented certain new and useful Improvements in a Combined Street- Sweeper and Collector; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a combined streetsweeper and collector which can be attached to carts of varying heights, so as to render the apparatus capable of easily traveling around corners or changing its direction in a limited space; and it relates more particularly to the means whereby the brush may be adjusted to suit the various conditions and classes of roads to be swept or raised into an inoperative position; and the invention further relates to the collection of the refuse and the means by which it is conveyed to a predetermined part of the collecting apparatus and removed from the collecting apparatus into the conveyance; and the invention consists of the construction and arrangement of the elements hereinafter more fully described, and more particularly pointed out in the claims and illustrated in the accompanying drawings, in WlllCll Figure 1 is a perspective view of the combined sweeper and collector. Fig. 2 isa plan view of the construction shown in Fig. 1 looking at it from the top. Fig. 3 is an end elevation of the sweeper and collector looking at them from the same end as shown in Fig. 1, the rotary brush in this view being positioned to engage the pavement. Fig. L is a similar view to Fig. 3, but looking at it from the opposite end to show the means for driving the Archimedean screws. Fig. 5 is a sectional view of the apparatus looking at it from the same end as Fig. at to show the driving mechanism for transmitting motion from the axle to the drive-shaft, the brush in this view being in contact with the pavement. Fig. 6 is asimilar view to Fig. 5 with the brush elevated from the pavement. Fig. 7 is a sectional view showing the clutch members for causing the revolution of the driving gearwheel with the axle. Fig. 8 is a view of the shifting-lever for the movable clutch member. Like letters of reference refer to like parts throughout the specification and drawings.

In carrying this invention into practice the brush 11, having a shaft (6, is mounted to revolve at the rear of the machine in such a manner as to sweep the refuse into the receptacle 5, having within it right and left Archimedean screws 0 c to convey the refuse from each end of the receptacle toward the center, so that it may be removed by the elevator (l and delivered into the cart or other conveyance to carry it away.

The elevator (Z consists of a series of buckets (7', fixed upon chains d, revoluble around the top and bottom sprocket-wheels (Z and (V, respectively, the bottom sprocket-wheels cZ* being fixed upon and revoluble with the shaft 0 of the Archimedean screws 0 a and the top sprocket-wheels (Z being mounted upon a shaft ll", journaled in the sides of the elevator-casing (1. The shaft 0 is so positioned that the mouth of the buckets when revolving around the shaft will pass close to the bottom of the dust-receptacle 7) and scoop up the refuse as they revolve. To facilitate the entry of the refuse into the receptacle, an inclined apron 7/ is hinged to it adjacent to the bottom of the opening I). This apron follows along the pavement in rear of the receptacle and in advance of the brush, so that the brush during its revolution will sweep the refuse up the apron and through the opening into the receptacle, where it is immediately engaged by the blades of the Archimedean screws and carried to the elevator, so that the buckets will scoop it up and carry it to the outer end of the elevator and then dump it into the carts or conveyances to receive it.

The ends of the brush-shaft a are mounted in radial arms 1'. oscillatingly connected to the main frame a, and journaled in the main frame a" is the screw-shaft 0, upon which is supported the dust-receptacle 7). The main frame is supported by the axle f of the roadwheelsf, by which it is revolved during their progress over the pavement, and loosely mounted upon the axleis a gear-wheel a, having a clutch member a" to engage with the clutch member 1/1 laterally movable upon the axlef and revoluble therewith. \Vhen the clutch member 11/ is positioned to engage with the clutch member 92 it will cause the united revolution of the gear-wheel n with the axle f. The gear-wheel w meshes with the gearwheel a, mounted upon an intermediate shaft g, journaled in the main frame a", so that when the clutch members are in engagement motion will be transmitted by the gear-wheels from the axle f to the shaft 9. Mounted upon the shaft gisa sprocket-wheel p, and mounted upon the brush-shaft a is a sprocket-wheel 9, around which is revoluble a sprocketchain 0 to transmit the motion of the shaft 9 to the brush. Mounted upon theshaft g is a gear-wheel g, and mounted upon the screwshaft 0 is agear-wheel g, meshing with the gear wheel 9, by which motion is transmitted from the shaft 9 to the Archimedean screws during the revolution of the brush.

The main frame (0 consists of two side members separated from each other by distancebars It, which hold them in their proper relative positions upon the axle f, and fulcrumed to one of the distance-bars IL is a lever l to actuate the clutch member m and move it respectively into and out of engagement with the clutch member 72 so that the shaft 'g may be caused to rotate with the axle f or allowed to remain stationary while the axle revolves.

To maintain the apron b in its relative position to the dust-receptacle b, chains 1 are connected to it and to the radial arms j for the brush-shaft, the chains being of such a length that they will raise the apron out of contact with the pavement as the brush is lifted into its inoperative position.

Fulcrumed to the main frame a" is an opcrating-lever 7:, and pivotally connected to the radial arms 3' is a link 5'. Fulcrumed to the main frame below the plane of the operatinglever is is a lifting-lever 0, the 'forward end of which is pivotally connected to the operatinglever k by a link and the rear end of which is pivotally connected to the link j. By moving the free end of the operating lever is downward in the direction indicated by arrow in Fig. & of the drawings it actuates the lifting-lever 0 to raise the brush from the pavement and by raising the free end of the operating-lever it actuates the lifting-lever to lower the brush into contact with the pavement. Connected to the lifting-lever 0 is a locking-plate 0, having a series of holes 0 to receive the locking-pin 0 When the operating-lever is adjusted to position the brush, it is held in its adjusted position by a lockingpin 0 inserted through one of the holes 0" of the locking-plate 0.

The main frame is fitted with two converging draft-bars f", united below the elevator and having a bolt 8, by which they may be attached to the cart or other conveyance. When the draft-bars are connected to the cart or other conveyance, they maintain the main frame continuously in the same position during the use of the apparatus and when they have been attached the brush can be moved into contactwith the pavement or raised out of engagement with it by the adjustment of the operating-lever.

Having thus fully described my invention,

\ what I claim as new, and desire to secure by Letters Patent, is
